The road cuts straight through the middle of it, dividing the old enclosure into two nearly equal halves, though you would never know it today. There is no visible trace of the rampart left to find.

The place appears in the historical record as the ancient parish of Rathculbin, recorded in the Red Book of Ossory, a medieval ecclesiastical register associated with the diocese of Ossory, under the variant spellings Rathgulby, Ragulby, and Rakylbyn. Shortly after the Norman Invasion, the townland was granted to a man named Ralph de Borard, who transferred its free chapel to the Priory of Kells. That chapel, along with its glebe, the land attached to support a parish church, was still listed among the priory's possessions in 1411. Writing in 1905, the historian William Carrigan noted the large circular rath as one possible location for the long-lost chapel, describing an earthen rampart that was much obliterated even then but still faintly traceable. Within what would have been its circuit, in a yard belonging to a Mr Hoyne, he observed the remains of an old house said to have been occupied by someone named Elliot around 1760. That house, dateable to the late sixteenth or early seventeenth century, survives as ruins in a farmyard on the north side of the road, and represents the only physical remnant of a layered history that the ground itself has otherwise swallowed entirely.
